Sink Bowl Flush Dry Food Waste Disposer {A FOOD WASTE PROCESS DEVICE FOR A SINK}

The present invention relates to a food waste disposer, and more particularly, a series of processes for grinding, drying, and storing food waste disposed of in a sink bowl immediately at the bottom of the sink bowl without additional movement is automated, resulting from corruption of food waste. It is a sink bowl-type dry food waste disposer that can prevent hygiene and pollution of sewage and minimize the amount of food waste.

In general, food wastes emitted from homes or restaurants often contain large amounts of water.

Therefore, it is easily decayed and has a bad effect on hygiene problems and the natural environment.

In recent years, the Food Waste Disposal Act has been enacted to separate waste into general waste, food waste, and other recyclable waste, and it is common practice for households and restaurants to put food waste in trash bags without leaching. have.

On the other hand, food waste is very watery, so even if it is completely packed in plastic garbage bags, if leachate leaks between the garbage bags or the garbage bags are fragile, the food waste is frequently exposed to the outside. It is true.

As a result, in hot seasons such as summer, there is a problem contrary to the purpose of protecting the environment because flies gather around the bags of food waste or provide an environment in which various bacteria breed.

In view of such a problem, commercially available dehydration apparatus or drying apparatus for removing moisture from food waste, or a treatment apparatus for microbial decomposition treatment of food waste is commercially available.

The use of such a food waste treatment device has the advantage of reducing the volume of food waste, thereby preventing environmental pollution and reducing the processing cost of food waste.

On the other hand, the sink is an essential facility of the kitchen, such as homes and businesses, and also prepares meals and washes the food left after the meal, it is also a source of various food wastes including water.

Therefore, there has been proposed a technology for treating the food waste discarded in the sink, which is installed in the drain of the sink to discharge the food waste through the sewer by crushing the food waste, there is also a problem causing environmental pollution.

The present invention is to solve the above problems, is installed in connection with the drainage path in the sink bowl lower portion of the sink crushing and drying the food waste drained from the sink to the sewage system, and do not discard the processed food waste to the sewage system The purpose of the present invention is to provide a sink-type dry food waste disposal system that can improve the sink and kitchen environment and prevent pollution of the sewage system by collecting and disposing through a prescribed food waste bag.

In accordance with an aspect of the present invention, there is provided a sink bowl-type dry food waste processor comprising: a pulverizer formed in communication with a sink hole and receiving food and water from the sink ball to crush the food; A transfer unit installed at the bottom of the grinding unit so as to linearly reciprocate and transfer the food waste crushed by the grinding unit; And, it characterized in that it comprises a drying unit for drying by heat while stirring the food waste transported by the transfer unit.

According to the sink bowl-type dry food waste processor according to the present invention, the food waste collected in the sink bowl is crushed and then quickly transferred to a drying drum for drying, so that the food waste can be hygienically treated within a short time in which bacteria cannot grow abnormally. have.

In addition, the food waste dried in the drying drum is automatically discharged by the operation of the stirrer to evenly mix the food waste contained in the drying drum to dry all the food waste.

In addition, since hot air from the hot air blower is supplied to the drying drum via the dry matter storage box, food wastes of size and physical properties that cannot be crushed by the crushing unit can be put together in the dry storage box and dried together. In addition, the hot air generated from the hot air fan is continuously heated every time and the drying operation is repeated every time before the hot air generated in the drum is supplied to the drum to increase the effectiveness of the hot air and the drum needs to be overly large. There is no need to operate the drying drum for a long time.

Therefore, according to the present invention, by putting the food waste contained in the dry container in the prescribed food waste bag, it is possible to keep the sink bowl, the sink and the kitchen environment clean and prevent contamination of the sewage.

Currently, municipalities have different ways to implement food waste and general waste. For example, even municipal food wastes with a drying rate of 75% or more may be disposed of in municipal waste bags, and municipal wastes may be disposed of with food wastes of 75% or more. There are also municipalities that are divided into municipalities, where dried food waste can be incinerated like ordinary garbage. This reflects the reality that local governments are hard to obtain landfills that are appropriate for each municipality, and the fact that natural environmental factors such as groundwater can be seriously contaminated by leachate generated from landfills of food waste. That is, the present invention is an invention that shows the result of satisfying such a law, and can significantly reduce the amount of food waste and increase the utility of landfills.

As shown in FIG. 1, the sink bowl-type dry food waste processor according to the present invention is to crush and dry food waste discarded in the sink bowl 1 of the sink, and through the cabinet 2 at the bottom of the sink bowl 1. Can be formed.

The present invention includes a crushing unit 100, a conveying unit 200 and a drying unit 300, and will be described in detail for each component.

The grinder 130 may be operated by a user's manual operation or sensing. For example, when the lid 112 is closed by closing the lid 112 in the grinding tank 110, the motor 132 is turned on. The motor 132 may be configured to operate off when the pulverization tank 110 is opened by the lid 112. As a sensor for detecting the closing and opening of the lid 112, various sensors such as a magnetic sensor may be used.

The lid 112 does not only perform a function of a sensor for generating a driving signal of the grinder 130, but blocks an upper portion of the grinder 110 to prevent odor of food waste, and the food waste splashes into the sink ball 1 when crushed. It also functions to prevent it from coming out.

The transfer unit 200 is installed at the bottom of the grinding unit 100 so as to linearly reciprocate and transfer the food wastes crushed by the grinding unit 100 to the drying unit 300, and the transfer guide 210, silicon, and the like. It is composed of a carrier 220 and a drive means having a waterproof, deodorizing function treated with.

The transfer guide 210 is provided with a space for the carrier 220 to linearly reciprocate therein, and also includes an input hole 211 into which food waste is input, a drain hole 212 for draining water introduced into the carrier 220, and a carrier. It consists of a discharge hole (213) for supplying the food waste transported by the 220 to the drying unit (300).

The length of the transport guide 210 should be at least three times the length of the carrier 220, the left end of the discharge hole 213 is greater than twice the length of the carrier 220 from the left end of the transport guide 210 It must be open from the point.

The transfer guide 210 has a box shape in which at least one side (left side in FIG. 3) is opened to assemble and separate the carrier 220, and is assembled to the cabinet 2 so that it can be disassembled.

The carrier 220 has a basket shape in which the upper and lower parts are opened and is installed to be movable in the transfer guide 210 to transfer the food waste introduced through the feeding hole 211 to the discharge hole 213.

The driving means is composed of a traction wheel 230 rotated in both directions by the motor, one end is fixed to the traction wheel 230 and the other end is passed through the transfer guide 210 to the traction wire 231 is fixed to the carrier 220 do. That is, as the traction wheel 230 rotates in both directions by the driving of the motor, the traction wire 231 is wound or unwound on the traction wheel 230, so that the carrier 220 and the inlet hole 211 of the transfer guide 210. It is to reciprocate between the discharge hole (213).

Although the traction wheel 230 may be driven by a separate motor, in the present invention, the traction wheel 230 may be configured to be driven by a motor driving the drum 310 of the drying unit 300. Will be explained clearly at the time of description.

On the other hand, the traction wire 231 is easy to move the carrier 220 to the discharge hole 213 side while being wound on the traction wheel 230, the carrier 220 on the discharge hole 213 side to the injection hole 211 side Since it will be difficult to return, a return member for returning the carrier 220 is further included.

The return member may be a weight 232 (refer to FIGS. 1 and 4) for returning the carrier 220 by its weight. The weight 232 is connected to the opposite side of the carrier 220 to which the towing wire 231 is connected. That is, when the winding force of the traction wheel 230 is greater than the weight of the weight 232, the traction wire 231 is wound on the traction wheel 230, but if the power is not applied to the traction wheel 230, the weight The carrier 220 returns to its original position by the weight of 232.

The transport path is determined by the one or more pinch rollers 233 so that the pull wire 231 does not twist when guiding the transport of the carrier 220.

The carrier 220 is driven to return to its original position when the lid 112 is opened.

The drying unit 300 may include a drum 310 containing food waste transported by the carrier 220, a hot air blower 320 for drying food waste by supplying hot air into the drum 310, and inside the drum 310. It consists of a stirrer 330 to evenly mix the food waste contained in.

The drum 310 is cylindrical, and two openings are formed at a circumference thereof, one of which is in communication with the discharge hole 213 of the transfer guide 210, and the other is in communication with the hot air blower 320. The opening through which the discharge hole 213 and the hot air blower 320 communicate with each other is not limited to that shown in the drawing.

The hot air blower 320 blows air raised to a high temperature to the drum 310 by sucking outside air and passing the heater. The suction port for sucking air into the cabinet 2 by the hot air fan 320 may be opened and closed in conjunction with the operation of the hot air fan 320.

The stirrer 330 includes a stirring blade 332 which rotates in both directions by the stirring motor 331 and the stirring motor 331.

As shown in Figure 5 and 6, the stirring blade 332 is a hub 332a, the hub 332a is fixed to the rotating shaft 331a to receive a rotational force from the stirring motor 331 through a gear train, etc. It is composed of a straight portion 332c formed symmetrically with each other in the portion and provided with a through hole 332b, and a bent portion 332d bent in one direction at an end of the straight portion 332c.

The stirring motor 331 is axially coupled with the stirring blade 332 to impart a rotational force to the stirring blade 332, as described above, may also impart a rotational force to the traction wheel 230. As shown in FIG. 7, the traction wheel 230 is connected to the stirring motor 331 through the clutch 233 and is configured to rotate by receiving power from the stirring motor 331 only when the carrier 220 moves forward and backward. . The clutch 233 transfers the power of the stirring motor 331 to the traction wheel 230 in the forward direction of the carrier 220 (in the direction of conveying food waste to the drum 310), but stirs when the carrier 220 moves backward. By removing the power from the motor 331 to allow the traction wheel 230 to rotate freely, the carrier 220 may be returned by the weight of the weight 232, or the stirring motor 331 may be reversed. It may be configured to assist the return of the carrier 220 by the weight of the weight 232 by slowing the traction wire 231 receives the power to rotate in the opposite direction from).

The drum 310 may have a structure in which one side is opened to remove the food waste, which has been dried, but in the present invention, it may be configured to discharge the food waste from the drum 310 by the stirring blade 332.

To this end, a duct 312 is formed at the periphery of the drum 310 to communicate with an inlet hole 311 (which becomes a discharge hole when discharging food waste), and a dry storage box corresponding to the free end of the duct 312 ( 400) is installed. The duct 312 and the dry storage container 400 are formed in fluid communication with the hot air blower 320 so that the hot air blown by the hot air blower 320 passes through the dry storage container 400 and then passes through the duct 312. Is introduced into the drum 310, when the drying is discharged, the stirring blade 332 is configured to rotate in the reverse direction (counterclockwise reference to Fig. 1) to push the dry matter inside the drum 310 toward the duct 312 side.

Odor and water vapor may be generated when the food waste is dried inside the drum 310, and the odor and water vapor may be discharged to the sewage system without discharging it to the kitchen through the sink bowl 1. On the downstream side, an exhaust pipe communicating with the exhaust fan 313 is provided.

In order to increase the drying effect, the heat transfer plate 340 may be further formed on the wall surface of the drum 310. The heat transfer plate 340 may be applied to a variety of things, such as heat generated by the power.

The food waste treatment method of the sink bowl-type dry food waste processor according to the present invention configured as described above is as follows.

Collect food waste left in the state in which the bowl is placed in the sink bowl (1) to wash dishes, and collects the food waste collected in the sink bowl 1 by opening the lid 112 in the crushing tank (110). . Previously, spoons and chopsticks can be visualized by the user, so screening is done. When the food waste is contained in the crushing tank 110, small iron pieces may be hidden in the food waste, and the iron pieces are adsorbed to the magnet 120 of the crushing tank 110.

When the lid 112 is closed for the processing of food waste, a grinding signal is applied to supply the power to the grinding motor 132, whereby the upper / under brackets 133 and 134 guided to the grinding mill 130 are assembled and fixed to the grinding tank. It rotates about the central axis (rotational speed is 1 rotation per second, for example). The food waste caught between the fixed upper bracket 133 and the rotating steel sheet grinder 130 passes through the steel sheet grinder 130 while being crushed and is contained in the bottom carrier 220.

Although not described in detail in the above-described configuration, when a small iron piece is caught between the fixed upper bracket 133 and the rotating steel sheet grinder 130 and the overload occurs in the grinder 130, the grinding motor 132 The power applied to the blocker is cut after a slight reverse rotation, and the grinder 130 is stopped and a warning sound is generated. Overload detection and driving stop and warning sound generation of such a grinder 130 will be readily available to those skilled in the art.

When the crushing unit 100 is crushed, the carrier 220 is set to the bottom of the crusher 130, and the food waste crushed by the crusher 130 is contained in the carrier 220.

The carrier 220 is crushed food waste and a small amount of water is contained together, the water is drained to the sewage system built in the existing sink through the drain hole 212, the food waste is drying unit through the carrier 220 Is transferred to 300.

When the transfer signal of the carrier 220 is generated, the stirring motor 331 is driven to rotate the stirring blade 332 in the clockwise direction of Fig. 1, by this rotation the traction wheel 230 is rotated clockwise. .

Accordingly, the traction wire 231 is wound around the traction wheel 230 so that the carrier 220 is transferred to the discharge hole 213 in communication with the drum 310. Of course, when the lid 112 is opened during the transport of the carrier 220, the traction wheel 230 is driven in reverse rotation so that the carrier 220 immediately returns to its original position in order to ensure the waterproof and deodorizing function. When the carrier 220 is returned, the traction wheel 230 does not substantially reverse the carrier 220 but rather slows the traction wire 231 so that the carrier 220 reverses by the weight of the weight 232. To perform.

Thus, the pulverization and transport of the food waste has been described, hereinafter drying will be described.

First, the dry matter storage box 400 separately contains food wastes that are dried and discharged from the drum 310, as well as food wastes that can not be crushed by the crusher 100 (foot thighs, chicken bones, shells, peaches, etc.) separately. Can be dry.

The above-mentioned wastes are classified as general wastes, not food wastes according to the current law. Therefore, they should be disposed of in general waste water-based bags. However, due to their low water content, the decaying characteristics are not the same as food wastes. Long term storage is not appropriate in reality. Especially in the case of separated households, nuclear family homes have a very small amount of general waste, so the above substances are very difficult to dispose of.

The hot air is forcedly blown by the hot air blower 320, and the path of the hot air is in the right side of the drum 310 (see FIG. 1)-the dry storage box 400-the left side of the drum 310-the inside of the drum 310. That is, the high temperature hot air forcedly blown by the hot air fan 320 first heats the right side of the drum 310 (which heats the drum 310 without directly heating the food waste), and passes through the dry storage box 400. While the dry matter (food waste, which was first dried in the drum 310, and discharged after the first drying in the drum 310, and the food waste, such as large jokbal bone, large clam shells directly put into the storage box through the drum 310) After drying, the left side of the drum 310 is heated, and the food waste which is introduced into the drum 310 and stirred inside the drum 310 is dried. Since hot air should be discharged as much as the air introduced into the drum 310, the air inside the drum 310 is discharged to the sewage system through the trap 3 by the blowing force of the discharge fan 313.

During the drying process, the food waste introduced into the drum 310 by the stirrer 330 is uniformly stirred, and this operation is as follows. The stirring blade 332 rotates in both directions by using the stirring motor 331 as a driving source to evenly mix the food waste or discharge the dried food waste to the outside of the drum 310.

First, upon stirring, the stirring blade 332 is rotated counterclockwise with reference to FIG. 1. When the stirring blade 332 rotates in the counterclockwise manner, the food waste inside the drum 310 is spread over the stirring blade 332 by the bent portion 332d of the stirring blade 332 and the stirring blade 332. When the rotation reaches a predetermined point, the food waste falls down through the through hole 332b and is mixed with the food waste at the bottom of the drum 310. As the rotation is repeated, the food waste inside the drum 310 is evenly mixed to uniformly dry all the food waste.

Drying may be controlled by a user's manual operation, a timer, or other electronic control device. When the drying is completed, the stirring motor 331 rotates as opposed to the drying time to discharge the dried food waste.

Therefore, the stirring blade 332 is rotated in the clockwise direction as shown in Figure 1, wherein the bent portion 332d pushes the food waste at the bottom of the drum 310 to the inlet (inlet hole 311) of the duct 312 Function to raise.

The food waste discharged to the duct 312 by the stirring blade 332 is stored in the dry storage box 400 along the duct 312.

Discharge operation can also be controlled by the user's manual operation, timer, and other electronic control devices, etc., when the discharge is complete and the amount of dried food waste is filled in the storage box 400 is put in an envelope every few days.
